Abstract: Color blindness, or color vision deficiency, is an inability to see the difference between certain colors. Men are more likely to be born with color blindness. Most people with color blindness can't distinguish between certain shades of red and green. Less commonly, people with color blindness can't distinguish between shades of blue and yellow. For that it’s a significant barrier to effective computer use. Several research works dealing with blind color user interfaces are currently conducted. However, requirements engineering for such interfaces is still missing. The work presented in this paper is part of an automated blind color user interface generation project which explores suitable input requirements document notations, simplifies the generating process, and outputs generated color blind user interface. It aims to define functional and nonfunctional requirements for powerful color blind user interface and their UML specification. Thus, different recent techniques that deal with these interfaces are selected according to their relevance and up to date, then they are analyzed, the lack of requirements engineering for these interface was stated, and a solution is proposed. It consists of requirements elicitation and specification with UML notations. A case study evaluating the proposed approach is presented. The obtained results confirm the power and positive impact of such requirements engineering on researches in this domain.

Abstract: The Goal Model (GM) of software is one of the important concepts in the software requirements specification, as it helps in representing the software goals and the relationships between them. Several research works were conducted to generate GM of software from its requirements document. However, the generated GMs merge behavior and soft goals aspects. This merging leaded to tangled and complex generated GMs that are difficult to maintain. The work presented in this paper proposes a GM formalism handling this insufficiency. It is part of an automated GM generating project where it focuses on the target GM. Thus, in this work, different recent techniques that automatically generate GMs are analyzed, their merging, tangling, and complexity of maintenance were stated, and a GM formalism facing these challenges is proposed. It separates goals clearly into behavior goals, soft goals, and constraints aspects. An evaluating case study, which is a partial concrete and real word domain requirements specification, is presented. This separation of concerns leaded to valuable results: complexity reduction, improvement of the understandability, simplicity of maintenance, and raising up the expressiveness power.

Abstract: As resistant microbial strains continue to appear, antibiotic-based therapies become less effective. Hence, development of non-antibiotic antimicrobial delivery systems, such as those containing chlorhexidine, is urgently needed for the prevention and treatment of infections. For many biological applications as well as for efficient therapy, controlling the release kinetics of these antimicrobials is crucial. In this study, chlorhexidine was loaded into silica nanoparticles via layer-by-layer (LbL) coating technique. Different polyelectrolytes including polyacrylic acid (PAA), poly(diallyldimethylammonium) chloride (PDDA), poly(allylamine hydrochloride) (PAH) and poly(4-styrenesulfonic acid) (PSS) were utilized in LbL coatings. Three types of coatings were studied: (1) PSS and PDDA (2) PAA and PAH (3) PSS and PAH. Zeta potential, transmission electron microscope, and a thermogravimetric analysis were used to characterize the nanoparticles. Acetate buffer pH 5 and PBS pH 7.4 were used as release media to assess the chlorhexidine release from nanoparticles. The chlorhexidine LbL-coated nanoparticles were effective in extending the duration of the medication release to 40 days. Chlorhexidine release was affected by pH of the release media and type of LbL coating, with a greater release at pH 5. PAA and PAH LbL coating had the highest amount of chlorhexidine release. This work illustrates that the LbL coating is an efficient technique for controlling the release of chlorhexidine from silica nanocarriers, with PAA and PAH coat

Abstract: Literature suggest that treatment of digital eye strain (DES) prescribed by health professionals is not highly effective in reducing the symptoms of it. This demands an additional management to be prescribed along with the current treatment for DES. Exercise is one of the potential emerging additional strategies in the conservative management of DES. Therefore, the purpose of this study was to estimate the influence of eye exercise (EE)among primary school students with DES. Methodology: A Computer Vision Syndrome Questionnaire (CVS-Q) score of 6 was used to identify the subjects with DES, followed by ophthalmologist examination. Then, the subjects were allocated into two groups. Group A (n = 15) received conventional therapy (CT) (artificial tears and the 20-20-20 rule) and EE (pencil push-ups, eye-rolling, and palming). Group B (n = 11) received CT. Both groups underwent treatment for a period of six weeks. Before and after treatment, CVS-Q was administered to all participants. Treatment outcome was analyzed using the Wilcoxon signed rank test and the Mann-Whitney U test. Findings: The results revealedtatistical significance within group A (p = 0.001), and across groups (p = 0.006), and statistical non-significant within group B (p = 0.104).These results suggest that exercise is beneficial in lessening the severity of DES among school students. Conclusion: The EE may be prescribed along with the CT to reduce the severity of DES among primary school students.

Abstract: The fluctuating and disorganized state of todays global markets is the result of several factors. COVID-19 is an illustration. Supply chain managers should re-evaluate their competitive strategy and leverage big data analytics in light of the rising volatility in demand and supply, rivalry among supply chain partners, and the requirement to deliver tailored goods and services (BDA). Supply chain firms require sophisticated BDA processes and procedures to provide useful insights from big data to better decision-making and supply chain operations, as many leaders in the sector have acknowledged the necessity for improving with data" (SCO). This research gives theoretical justification for the influence that BDA has on SCO.

Abstract: The purpose of this paper is to examine the role of customers’ perceived value in mediating the relationship between Electronic Service Quality (ESQ) and customer satisfaction in online banking in Malaysia. The research model is developed based on the disconfirmation theory. Non-probability purposive sampling was adopted for data collection. A cross-sectional technique with a self-administered questionnaire was applied. The unit of analysis in this study is bank customers using online banking in Selangor, Malaysia. One hundred twenty-eight usable responses were received and analyzed. The Statistical Package for the Social Sciences (SPSS) was applied to analyze the data. Findings showed that the variance in customer satisfaction can be significantly explained via E-service quality dimensions (R2 = 0.52). The ease of use, security, reliability, responsiveness (ESQ) have a significant and positive impact on customer satisfaction among online banking users (p = 0.000). Furthermore, it was found that the customers’ perceived value significantly mediates the relationship between E-service quality and customer satisfaction (p-value = 0.0004). The experimental findings for this paper strengthen and expand the theoretical understanding of the relationship between ESQ, customer perceived value, and customer satisfaction that helps the banks in Malaysia to perform more successfully in the rapid business environment.This study also contributed to diminishing the gap in the ESQ literature between developed and developing countries, especially in the Malaysian context.

Abstract: Worldwide, more health care facilities are adapting the use of electronic health record (EHR). Healthcare providers (HCP) have different perceptions toward the use of EHR. To investigate the perception of three classes of HCP in Saudi Arabia toward using EHR, a questionnaire (targeting satisfaction, easiness, and benefits of use as major perception indicators) was prepared. The questionnaire was assessed by an expert panel for content validity. The questionnaire internal consistency was examined using Cronbach’s alpha. 108 physicians, physical therapists (PT) and respiratory care therapists (RT) from different hospitals in Saudi Arabia answered the questionnaire. Most of respondents perceived EHR systems as beneficial and made work easier. Most HCP were satisfied with the use of EHR, however, with the use of EHR more time was needed to finish the work. Age, experience, job, and job rank of HCP are of different importance in determining responses, perception, and obstacles of using EHR. Moreover, the perception of using EHR seems to be field specific. There is a positive perception among Saudi Arabia HCP about EHR use.

Abstract: Abstract: Very few studies have thus far evaluated the impact of various processing and preservation techniques (blanching, frying, freezing, dehydration, and sun drying) on the levels of total phenolics, flavonoids, and antioxidant activities of okra. The primary objective of this study was to evaluate the effects of different processing and preservation methods on the levels of phenolics, flavonoids, and antioxidant activities of okra. The ethanolic extracts of each sample were analyzed before and after preservation and storage for a period of three months. The results showed a significant improvement (p < 0.05) in total phenolic content (134.1 mg GAE/100g) and DPPH (1-1-diphenyl1-2- pricrylhydrazyl) scavenging activity (IC50 value of 3.0 mg/mL) in blanched okra when compared to fresh okra (86.35 mg GAE/100g and IC50 value of 3.8 mg/mL, respectively). Fresh okra exhibited the highest flavonoid content (105.75 mg QE/100g), while sun-dried okra samples stored for three months exhibited a decrease in total phenolic content (14.45 mg GAE/100g), total flavonoid contents (13.25 mg QE/100g), reducing power activity (23.30%), and DPPH scavenging activity (IC50 value of 134.8 mg/mL). The DPPH inhibition activities of all okra treatments showed a significant and positive correlation with the okra phenolic and flavonoid content (r = 0.702 and 0.67, respectively). The reducing power activity (%) of okra treatments exhibited a strong correlation (r) with phenolic contents (r = 0.966), and the correlation with flavonoid contents was 0.459. Generally, different processing and preservation methods of okra revealed that the impact on total phenolic and flavonoid contents, as well as antioxidant activities, was slightly significant among samples preserved using the same method during storage. In addition, blanched and frozen okra resulted in the highest retention of phenolic contents and antioxidant activities.
